A pilot program to screen passenger aircraft cargo for explosives will be launched later this summer at San Francisco International Airport (SFO) by the U.S. Department of Homeland Security (DHS).Known as the Air Cargo Explosives Detection Pilot Program, the effort will be conducted at SFO air cargo facilities under a collaboration between DHS’s Science and Technology (S&T) Directorate and the Transportation Security Administration (TSA).The $30 million cargo explosives screening pilot program will later be expanded to two other – as yet unannounced – U.S. airports.
